16:21 Therefore, behold, I will this once {l} cause them to know, I will cause them to know my hand and my might; and they shall know that my name [is] JEHOVAH.
(l) They will once again feel my power and mercy for their deliverance that they may learn to worship me.
16:21 Therefore - Because all the mercy I have shewed them, will not learn them to know my might, I will once for all make them to understand it, by the dreadful strokes of my vengeance. And - They shall know that my name is Jehovah; that I am not such a one as their idols, but one who have my being from myself, and give life and being to all other things, and have all might and power in my hand, and can do whatsoever I please.
16:14-21 The restoration from the Babylonish captivity would be remembered in place of the deliverance from Egypt; it also typified spiritual redemption, and the future deliverance of the church from antichristian oppression. But none of the sins of sinners can be hidden from God, or shall be overlooked by him. He will find out and raise up instruments of his wrath, that shall destroy the Jews, by fraud like fishers, by force like hunters. The prophet, rejoicing at the hope of mercy to come, addressed the Lord as his strength and refuge. The deliverance out of captivity shall be a figure of the great salvation to be wrought by the Messiah. The nations have often known the power of Jehovah in his wrath; but they shall know him as the strength of his people, and their refuge in time of trouble.
